EXCLUSIVE: Rep. Carlos Giménez, R-Fla., is urging Department of Homeland Security Secretary Alejandro Mayorkas to reconsider allowing four senior border officials to testify before Congress about the migrant crisis.

"This crisis is absolutely unsustainable and is a direct result of the failed open-border policies [the Biden Administration] has pursued," Giménez says in the letter, sent to Mayorkas following an in-person meeting held in Miami with the DHS chief along with Reps. Maria Salazar and Mario Diaz-Balart.

He continues: "I urge you to reconsider this decision and allow your Chief Patrol Agents and honorable law enforcement officers the right to share their experiences with the American people."

Giménez says it was important for the American people to hear directly from these officials "on the protocols in place, processes, and the actual day-to-day enforcement priorities from those on the ground, protecting our country."

Fox News Digital was told that during the meeting Mayorkas was not able to answer basic questions posed by the GOP members in attendance, including the number of illegal migrants residing in the U.S. currently.

The Biden administration announced that program for Venezuelans in October, which allowed a limited number to fly directly into the U.S. as long as they had not entered illegally, had a sponsor in the U.S. already and passed certain checks.
